can only point to the North Pole, a 0, or to the South Pole, a 1. If you were a qubit you could point anywhere in the world and make a mixture of a 0 and a 1. Due to the ability to be 0’s and 1’s qubits can check multiple solutions at the same time which makes them significantly more powerful than regular bits.

Какие преимущества имеет квантовый компьютер?

катализатором. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.

Каким образом происходит катализ реакции?

adsorbed on the metal catalyst. Under adsorption the molecule is deformed and the additional energy connected with an adsorption state arises. Therefore the less energy for molecule dissociation is required.

After blowing through the reactor 1 by using Ar and He (T=550-1000°С) CH4 is fed. CH4 is sorbed by the active catalyst centers where the reaction 1 occurs and carbon like carbon nanotubes and H2 are formed. This method is called chemical vapor deposition or shortly noted as a CVD method.

The nanocomposite FeNi3/C may be used as a catalyst for growing CNs. Metal nanoparticles are uniformly distributed and promote the CN growth. The vapor deposition method using the mixture CH4 and H2 employs. In the SEM photo, the tube containing a lot of carbon nanotubes can be observed. The tube diameter is about 3 mkm.
